Xaml 如何在UWP中的图像鼠标上更改图像,xaml,xamarin,uwp,xamarin.uwp,Xaml,Xamarin,Uwp,Xamarin.uwp,在仪表板上，我有一个图像，例如-ManageUser.png。所以，鼠标悬停，我想在UWP中更改图像（将图像替换为MnageUserBright.png）我只有图像代码您可以在该元素上使用PointerEntered事件，因此当用户在图像上移动鼠标指针或手指时，您可以触发一些代码来替换图像：当用户将其指针移出图像时，您需要通过处理PointerExited事件来执行相反的操作，以将原始图像设置回原处。谢谢@Rafeal，我建议使用所有xaml代码来完成此操作第一件事是安装Micro

在仪表板上，我有一个图像，例如-ManageUser.png。所以，鼠标悬停，我想在UWP中更改图像（将图像替换为MnageUserBright.png）

我只有图像代码

您可以在该

元素上使用

PointerEntered

事件，因此当用户在图像上移动鼠标指针或手指时，您可以触发一些代码来替换图像：

当用户将其指针移出图像时，您需要通过处理

PointerExited

事件来执行相反的操作，以将原始图像设置回原处。

谢谢@Rafeal，我建议使用所有xaml代码来完成此操作

第一件事是安装Microsoft.Xaml.Behaviors.Uwp.Managed。如何安装请参见：

这种方法是在用户鼠标进入时使用故事板更改图像源

定义两个故事板

       <Border.Resources>
           <Storyboard x:Key="EnterStoryboard">
               <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Image" Storyboard.TargetProperty="Source">
                    <ObjectAnimationUsingKeyFrames.KeyFrames>
                        <DiscreteObjectKeyFrame KeyTime="0:0:0" Value="assets/click_cursor_mouse_pointer_select_128px_1225441_easyicon.net.png"></DiscreteObjectKeyFrame>
                    </ObjectAnimationUsingKeyFrames.KeyFrames>
               </ObjectAnimationUsingKeyFrames>
           </Storyboard>
            <Storyboard x:Key="ExitStoryboard">
               <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Image" Storyboard.TargetProperty="Source">
                   <ObjectAnimationUsingKeyFrames.KeyFrames>
                        <DiscreteObjectKeyFrame KeyTime="0:0:0" Value="Assets/click_cursor_mouse_pointer_select_121.7433808554px_1193623_easyicon.net.png"></DiscreteObjectKeyFrame>
                   </ObjectAnimationUsingKeyFrames.KeyFrames>
               </ObjectAnimationUsingKeyFrames>
            </Storyboard>
        </Border.Resources>

并将图像置于边框上

    <Border>
        <Border.Resources>
            <Storyboard x:Key="EnterStoryboard">
                <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Image" Storyboard.TargetProperty="Source">
                    <ObjectAnimationUsingKeyFrames.KeyFrames>
                        <DiscreteObjectKeyFrame KeyTime="0:0:0"
                                                Value="manage_user.png" />
                    </ObjectAnimationUsingKeyFrames.KeyFrames>
                </ObjectAnimationUsingKeyFrames>
            </Storyboard>
            <Storyboard x:Key="ExitStoryboard">
                <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Image" Storyboard.TargetProperty="Source">
                    <ObjectAnimationUsingKeyFrames.KeyFrames>
                        <DiscreteObjectKeyFrame KeyTime="0:0:0"
                                                Value="Assets/normal.png" />
                    </ObjectAnimationUsingKeyFrames.KeyFrames>
                </ObjectAnimationUsingKeyFrames>
            </Storyboard>
        </Border.Resources>
        <Image x:Name="Image"
               Source="manage_user.png"
               Height="120" Width="120" Margin="176,31,534,84" />
    </Border>

使用事件触发器

        <interactivity:Interaction.Behaviors>
            <core:EventTriggerBehavior EventName="PointerEntered">
                <media:ControlStoryboardAction Storyboard="{StaticResource EnterStoryboard}" />
            </core:EventTriggerBehavior>
            <core:EventTriggerBehavior EventName="PointerExited">
                <media:ControlStoryboardAction Storyboard="{StaticResource ExitStoryboard}" />
            </core:EventTriggerBehavior>
        </interactivity:Interaction.Behaviors>

代码都是用xaml编写的。你应该替换源代码

<Grid>
    <Border>
        <Border.Resources>
            <Storyboard x:Key="EnterStoryboard">
                <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Image" Storyboard.TargetProperty="Source">
                    <ObjectAnimationUsingKeyFrames.KeyFrames>
                        <DiscreteObjectKeyFrame KeyTime="0:0:0"
                                                Value="assets/click_cursor_mouse_pointer_select_128px_1225441_easyicon.net.png" />
                    </ObjectAnimationUsingKeyFrames.KeyFrames>
                </ObjectAnimationUsingKeyFrames>
            </Storyboard>
            <Storyboard x:Key="ExitStoryboard">
                <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Image" Storyboard.TargetProperty="Source">
                    <ObjectAnimationUsingKeyFrames.KeyFrames>
                        <DiscreteObjectKeyFrame KeyTime="0:0:0"
                                                Value="Assets/click_cursor_mouse_pointer_select_121.7433808554px_1193623_easyicon.net.png" />
                    </ObjectAnimationUsingKeyFrames.KeyFrames>
                </ObjectAnimationUsingKeyFrames>
            </Storyboard>
        </Border.Resources>
